A car manufacturer organized a test drive of two of its prototypes. Each driver test both prototypes and asked if he or she liked the prototype. If the driver did not like the prototype, he or she was asked if the prototype's performance was the main reason. A driver did not like a prototype because of its performance 180 times, whereas only half as often a driver did not like a prototype because of some other major reason. How many test drivers were there?

1. 120 people liked both prototypes.2. As many people liked neither prototypes as like both of them.
